GB 855 Nimble and versatile 855 FORWARDERS Optimizes your profitability 855 Komatsu 855 is not only a new all-round forwarder. It is also a forwarder in an entirely new and unique class in terms of everything from productivity and low environmental impact to cost efficiency and operator ergonomics. Here are just a few of the most important benefits: Engine Operator environment The powerful SCR engine based on our special E3 power technology that minimizes NOx emissions (nitrogen oxides) and provides unsurpassed fuel economy. Additional benefits include reduced engine noise and a strong torque for hard work to cleaner engine oil. Noise reduction can be explained by variable fan control where the new, larger engine fan can run at exactly the speed required for cooling. The all-new cab is higher, wider, has more legroom and more storage space. The feeling of more space inside the cab is striking. The large glass surfaces give improved visibility upwards and to the sides and makes crane operation easier and more relaxing. The cab is designed to provide a quiet operator environment. As an option there is a new driver’s seat that provides superb comfort and work area and offers a variety of personal adjustments and settings. Control system Transmission With Komatsu 855, you get the MaxiXplorer control system that combines simplicity, power and functionality that is unparalleled in the market. The system gives you a leading machine control – engine, transmission, crane, lights, wipers, etc. – that can be easily adjusted, fine-tuned and adapted to the operator’s needs and desires. Komatsu 855 has brand new hand controls, ergonomically designed and well equipped. With Komatsu 855, you get powerful traction of 164 kN and unique interaction between the engine, control system and transmission. A design that ensures you get the most out of your machine at all times. Examples are cruise control, several preset and work optimized driving modes, extra traction on steep terrain and over obstacles. The result is maximum productivity and maximum deployment of each horsepower and liter of diesel. Eco-friendly and fuel efficient The powerful new SCR engine both minimizes emissions and optimizes fuel economy. Tomorrow’s profit machine is here Work optimized transmission The new HST transmission with traction of 164 kN gives increased performance through the unique interaction with the control system and the engine. ORFS couplings All critical hydraulics use ORFS couplings, which reduces the risk of leaks and downtime. The new cab has been designed to be quieter and provide a more highperformance operator environment as well as more storage space. To develop a completely new, ultra modern and productive forwarder is an achievement. But to do it based completely on the end customers’ wishes is an even greater achievement. Komatsu 855 is the result of an extensive study into the daily needs of individual machine owners and operators. This has produced an all-round forwarder offering outstanding ergonomics, productivity and cost-effectiveness. Take for example the 855’s new SCR- The full power of MaxiXplorer gives you everything from more accurate and more efficient machine control to marketleading operating and production reports. 855 based engine, which both minimizes emissions and maximizes fuel efficiency. To that you can add improvements in terms of both an impressive torque and cleaner engine oil. Service costs are cut further by the addition of tight-seal ORFS couplings and a minimized number of lubrication points. A groundbreaking feature when it comes to getting the most out of the machine is 855’s new transmission and its unique interaction with the engine and MaxiXplorer control system. In real terms this gives you benefits such as cruise control, multi work-optimized driving modes and the availability of extra traction that minimizes stalling, reversing and regripping on slopes and over difficult obstacles. And speaking of power, thanks to the 855 being equipped with the full functionality of MaxiXplorer, you also get one of the most modern operating and production report systems. On the Komatsu 855, productivity Our unique bogie solution, Komatsu Comfort Bogie, gives you superb mobility and stability. is also uniquely synchronized with ergonomics. A prime example is the new, silent and spacious cab, specially designed to make the operator’s work with continual crane movements as simple and easy on the body as possible. The result is a forwarder that delivers equal measures of outstanding job satisfaction and profitability. The kind of profitability that modern forestry demands.

High productivity, low operating costs, innovative technology, excellent operator environment – these are just a few examples of the advantages that earn Komatsu forestry machines a place among the best in the world. Behind all this is a highly-focused strategy to continually build upon the advantages of owning a Komatsu forwarder. A strategy based on the following principal ideas. Ergonomics Your forwarder is a mobile work environment where the operator’s opportunities to perform optimally without tiring are a decisive factor for success. This is an important reference point that has helped us develop the important ergonomic advantages of Komatsu forwarders. Good examples are the stability and the operator environment with its perfect view whether driving or operating the loader. Economy The ambition to maximize profitability is one of the most important driving forces in the further development of Komatsu’s forwarders. Each small improvement that increases productivity and reliability, reduces costs, or saves time is of interest. Tangible and quantifiable examples from today’s Komatsu forwarders include energy-efficient engines, high reliability, and unmatched high productivity per unit of time. Productivity Fast and competent service has a direct bearing on the performance and economy of any forestry machine. Our extensive service network provides you as a Komatsu owner with a sense of security. Well-trained technicians – Komatsu experts – provide additional assurance. Another benefit is ProSelect, our special line of accessories and consumables. The range is based on a selection of items that are all of the highest quality and designed for both Komatsu and other brands of professional forestry machinery. Environment More work in less time. This is something we often hear from contractors who switch from competing brands to Komatsu forwarders. And there are many reasons behind this, both large and small. The most important include the high-performance operator environment, superior loader geometry, and great maneuverability and speed. FPSB1015-00 Customer Support Forests are an essential and fragile element of the global ecology. This is why every new Komatsu product, and all its component parts, is examined with an eye to both the short-term and long-term environmental effects. This has resulted in real environmental improvements such as highly-effective exhaust emission control and low, evenlydistributed ground pressure in Komatsu forwarders. Environmental considerations also permeate our broad range of accessories and consumables, such as our special, rapidly biodegradable oils. Global Experience Komatsu forwarders can be found the world over. Consequently, they have been adapted to deliver optimum profitability regardless of working conditions. The same fundamental idea lies behind the global service and dealer network that provides support to thousands of Komatsu owners on a daily basis.
